Description and Introduction

18 V, 6 mA, low noise preamplifier for tape playback system The LM1897N is a carrier-current transmitter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Type:** Carrier-Current Transmitter  
- **Package:** DIP (Dual In-line Package)  
- **Operating Voltage:** Typically operates at **12V**  
- **Modulation:** AM (Amplitude Modulation)  
- **Frequency Range:** Designed for power-line communication applications  
- **Output Power:** Suitable for low-power carrier-current transmission  

### **Descriptions:**  
The LM1897N is designed for transmitting data or audio signals over existing AC power lines. It modulates the input signal onto a carrier frequency, allowing communication through standard electrical wiring.  

### **Features:**  
- **Carrier-Current Transmission:** Enables communication over AC power lines.  
- **AM Modulation:** Supports amplitude modulation for signal transmission.  
- **Low-Power Operation:** Designed for efficient power-line communication.  
- **DIP Packaging:** Easy integration into circuit boards.  
- **Wide Operating Voltage:** Compatible with standard power supplies.  

This IC is commonly used in applications such as home automation, intercom systems, and remote control via power lines.
